CHARLES W. HOTTMAN, OF PHILADELPHIA,

PENNSYLVANIA, ASSIGNCR OF ONE-HALF TO y CHRISTOPHER OFFENHAUSEB, OFPHILADELPHIA, PENNSYLVANIA.

MACHINE FOR CUTTING CABBAGE.

Specification of Letters Patent.

Patented Sept. 8, 1908.

T o all 'whom it may concern:

Be it known that I, CHARLES W. HOTT- MAN, a subject of the Emperor ofGermany, having declared his intention of becoming a citizen of theUnited States, residing at Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Machines for Cutting Cabbage, of which the followingl isa specification,

My invention relates to improvements in devices for slicing vegetables,particularly cabbage, and is designed to overcome the dead center commonto cutters in which rotary knives are employed and thereby obviate thecentral grinding action which not only hasa tendency to bruise theproduct but also tends to retard the free cutting action of the knives.

My invention further embodies a means for adjusting the knives withrespect to the plate by which they are carried for the purpose of gagingthe thickness of the slices to e severed from the mass of material actedupon.

My invention will be more fully understood by reference to theaccompanying drawings, in which:

Figure 1 illustrates a plan view of my vegetable cutter. Fig. 2represents a front elevation of same. Fig. 3 denotes a vertical sectionon a line 3 3 of Fig. 1. Fig. 4 shows a detached lan view of therotatable knife plate, the {nives being removed to show the shape of theopenings formed to receive them. Fig. 5 illustrates a detached plan viewof the knives and the spider by which they are supported. Fig. 6represents a transverse section of the knife plate with the knives inposition the section being taken approximately on line 6-6 of Fig. 4.Fig. 7 shows an enlarged section of a portion of the knife plate and aportion of one of the knives the purpose of which is to illustrate therelative position of one with respect to the other, and Fig. 8illustrates a section similar to that shown in Fig. 6 except that themeans for supporting and adjusting the knives has been slightlymodified.

Referring to the reference letters of the drawings, A, represents thehopper; B, the cutter plate; C, the vertical shaft on which the cutterplate is fastened; I), the horizontal driving shaft; F, the fixedvertical shaft; and, G, the bracket carrying the shaft C.

l, The lshaft C, is mounted in suitable bearings in the bracket G, andis provided with a pinion 7L, which meshes with a gear wheel II,fastened to the fixed shaft F. The bracket G, is connected to a bevelpinion E', by means of a sleeve c which loosely surrounds the shaft F,but is fixedly secured both to the bevel pinion and to the bracket. Thebeveled pinion E', meshes with a corresponding gear E, which is mountedupon a driving shaft D, rovided respectively with fast and loose pu leysD and D2. rPhe shaft D, is journaled in bearings I' I', projecting froma bed plate I, which is also rovided with a column I2, which supportstIie fixed shaft F. The hopper A, is sup orted by uprights A', A',projecting from tlie bed plate I, and is provided with an inclined chuteA2, to carry off the finished product.

cent-shaped openings B', in which rest the knives B3. These knives arefastened to a spider as shown in Fig. 5, the same consisting of a hubB2, having an opening h3, which embraces a corresponding hub B5, on thecutter late B, and arms b2, b2, etc., to which the nives B3, arefastened. The spider together with the knives is vertically adjustablewith respect to the plate B, for the purpose of gaging the thickness ofcut, and to this end is provided with a special spring S, locatedbetween the plate and the hub B2 -of the spider and tending normally topress the latter down. The hub B5, is threaded at or near the bottom toreceive a nut BG, which bearing against the bottom of the hub B2, may beturned to force the spider upwards against the action of the spring S. Asimilar construction is shown in Fig. S, except that the knives B3, aremounted upon independent lates 612, 612, which are fastened to studs L,and these are held by projecting arms K, K, connected to or forming partof the hub of plate B. The adjustment is similarly made by means of nutsM, M, acting against the action of springs S', S'.

The operation of the machine is as follows: IVhen the shaft D, isrotated it imparts a rotary motion to the bracket G, through the mediumof the bevel gears E, and E', and as the shaft C, is journaled in thebracket G, it is also turned and describes a circle concentric to thewall or rim of the hopper. I/Vhile this rotary motion of the shaft C andbracket G, is taking place the shaft C, is also caused The cutter plateB, is provided with cresto turn in its bearings by the pinion h, on thel and rovided with bearings to receive the ro shaft C engaging a gear H,iixedly secured to the stationary shaft F, and thus it Will be seen thatthe cutter plate B, is given two motions, one on its own axis andanother on an axis of which the shaft F, is the center.

Having described my invention what Il claim and desire to secure byLetters Patent is:

- A vegetable cutter comprising a hopper, a cutter plate arranged belowthe hopper, a rotatable shaft supporting said cutter plate, a bracketloosely mounted upon a fixed shaft tata le shaft, a gear Wheel securedto the fixed shaft, a pinion in en agement therewith secured to therotatable s aft, a bevel pinion fastened to said bracket and a bevelgear engaging the same mounted upon a shaft suitably driven,substantially as specified.
